The overarching initiative progress report has now been published and is available here. This will now be sent to initiative sponsors for their feedback but feedback here is also welcome.

The coming year promises an upward shift in apparent momentum as a result of significant work over the past three years with the release of databank holdings and benchmarks and an exciting workshop to be held in the summer - for more details on the latter watch this space in a few days time.

We will also continue to work with partner activities to further mutual aims.

Early in January a meeting of all groups involved in the initiative was held to discuss progress to date and future plans. The minutes from this meeting can be found here. The annual progress reports were discussed (more on this at months end). Also, new terms of reference were adopted for all groups (see the group pages at surfacetemperatures.org). The coming year promises many new, exciting, developments. Amongst others we expect to see:

Release of the version 1 databank which will consist of c.32,000 stations

Development and release of benchmarks

A workshop held jointly with SAMSI and NCAR on developing novel approaches to dataset homogenization

As mentioned back in the summer a paper led by Chris Merchant of Reading University on all aspects of surface temperatures arising from a workshop of the Earthtemp initiative had been submitted to the Open Access EGU journal Geoscientific Instrumentation, Methods and Data Systems. This was accepted and formally published just before Christmas.

The abstract is:

Surface temperature is a key aspect of weather and climate, but the term may
refer to different quantities that play interconnected roles and are observed
by different means. In a community-based activity in June 2012, the EarthTemp
Network brought together 55 researchers from five continents to improve the
interaction between scientific communities who focus on surface temperature
in particular domains, to exploit the strengths of different observing
systems and to better meet the needs of different communities. The workshop
identified key needs for progress towards meeting scientific and societal
requirements for surface temperature understanding and information, which are
presented in this community paper. A "whole-Earth" perspective is required
with more integrated, collaborative approaches to observing and understanding
Earth's various surface temperatures. It is necessary to build understanding
of the relationships between different surface temperatures, where presently
inadequate, and undertake large-scale systematic intercomparisons. Datasets
need to be easier to obtain and exploit for a wide constituency of users,
with the differences and complementarities communicated in readily understood
terms, and realistic and consistent uncertainty information provided. Steps
were also recommended to curate and make available data that are presently
inaccessible, develop new observing systems and build capacities to
accelerate progress in the accuracy and usability of surface temperature
datasets.

If you are interested in broader aspects of the surface temperatures problems and issues than just land surface air temperatures or how ISTI may fit into the whole I would encourage you to read the paper (caveat emptor: I am a co-author). The paper is available at doi:10.5194/gi-2-305-2013. It contains a mix of scientific, practical and development activities which taken as a whole would significantly improve our ability to understand all aspects of global surface temperatures.
